M009T71779 | Genuine Cummins® Starter Motor 38MT 12V

1. Crank the engine

• Spins the engine’s crankshaft and flywheel to initiate the combustion process.

2. Enable engine ignition

• Allows fuel and air to be ignited, so the engine can start running on its own.

3. Provide reliable starting

• Delivers high torque quickly to turn over the engine, especially in cold conditions or with larger engines.

4. Protect the engine

• Designed to disengage automatically once the engine starts, preventing damage.

1. Engine won’t crank

• Turning the key or pressing the start button does nothing, even though the battery is good.

2. Clicking or grinding noises

• A single click, rapid clicking, or grinding sound when trying to start can indicate worn gears, a failing solenoid, or internal starter issues.

3. Intermittent starting

• The engine sometimes starts and sometimes doesn’t, often due to worn brushes, bad solenoid, or loose connections.

4. Starter runs but engine doesn’t turn

• The starter motor spins, but the pinion gear fails to engage the flywheel.

5. Smoke or burning smell

• Overheating from excessive attempts to start or electrical issues can produce smoke or a burnt odor.

6. Dashboard lights dim when starting

• Indicates the starter is drawing excessive current due to internal resistance or binding.
